Easy Clean is what is on the container.
I think it's the same thing as one-step. Like I said, legally they can't be packaged as "sanitizers" but they do sanitize. I actually prefer star-san now, and it is labeled as a sanitizer, too.
From a website selling Easy Clean:
What is the difference between a sanitizer and a cleanser?
In the U.S.A., the word sanitizer is a legal term defined by the Environmental Protection Agency. In order for a product to be called a sanitizer in promotional literature or on its packaging, that product must be approved by the EPA, assigned a registration number, and have an open file maintained with the EPA. Unless a company would like to invest an enormous amount of capitol in this process (or use another company's product through a process called "sub-registration"), they may not call their product a sanitizer.
If you purchase a bottle of bleach from the grocery store, unless it shows an EPA registration number on the front of the label, it is not a sanitizer. However, it will certainly be a good cleanser (although somewhat hazardous, not environmentally sound, and it will require rinsing).
Is Easy Clean (One Step) a sanitizer?
Read the above question and draw your own conclusions. Easy Clean (One Step) has been used with excellent results since 1992.
For best results, Easy Clean (One Step) requires a 30 second contact time.
If you feel you must sanitize equipment and bottles for added protection after cleaning, use your favorite sanitizer or use 2 oz of sodium or potassium metabisulphite and mix with 1 gallon of water. Coat all surfaces and remove excess by draining or let drip dry. There is no need to completely dry sulphite solution before using equipment or filling bottles with wine or beer.
